try Shark Aquarium & Pet Center on Rt.22 in Union, NJ (908) 687-5111. altho i would kinda doubt it from what i've seen in the past but they should try to live up to their name, i guess.
the store is literally a stone's throw from the GSP and Union Toll Plaza. westbound side i believe. basically a FO store the last time i was in there (a year ago).
